Problems solved by technology

Golf clubs and many other ball striking devices can encounter undesirable effects when the ball being struck impacts the ball striking head away from the optimum location, which may be referred to as an “off-center impact.” In a golf club head, this optimum location is, in many cases, aligned laterally and / or vertically with the center of gravity (CG) of the head.
Even slightly off-center impacts can sometimes significantly affect the performance of the head, and can result in reduced velocity and / or energy transfer to the ball, inconsistent ball flight direction and / or spin caused by twisting of the head, increased vibration that can produce undesirable sound and / or feel, and other undesirable effects.

Abstract

A head for a ball striking device includes a face having a striking surface and a rear side located behind the face, a rear member connected to the rear side of the face member and having a front surface confronting the rear side of the face member, and a resilient material separating the rear member from the face member, such that the resilient member engages the rear member and the face member and is configured to transfer momentum between the face member and the rear member. The face member has projections extending rearwardly from the rear side of the face member proximate the heel and toe sides of the head. The rear member has receivers in the front surface on the heel and toe sides of the head, where the projections are received in the corresponding receivers.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority to, and is a continuation-in-part of, co-pending U.S. patent application Ser. No. 13 / 308,079, filed Nov. 30, 2011.TECHNICAL FIELD[0002]The invention relates generally to ball striking devices, such as golf clubs and golf club heads, utilizing features for transfer of energy and / or momentum. Certain aspects of this invention relate to golf club heads having a rear member configured to transfer energy and / or momentum to the face upon an impact on the face.BACKGROUND[0003]Golf clubs and many other ball striking devices can encounter undesirable effects when the ball being struck impacts the ball striking head away from the optimum location, which may be referred to as an “off-center impact.” In a golf club head, this optimum location is, in many cases, aligned laterally and / or vertically with the center of gravity (CG) of the head.
